Why do perfectly good storms keep dissipating over Central Illinois??

you know, I get pissed about that too... I see a big line of thunderstorms heading towards Ft. Campbell... and they dissipate 10 miles before they get here... what a rip-off!!

but seriously, I would go to www.weather.com and ask an expert.

Same here, I have seen this in my area for at least one decade.Major storms and then once to my county's border they dissipate to nothing (especially when moisture is needed). Many of my friends notice the same thing here In Shelby County Indiana. We call it, the now you see it now you don't storm system. I live at the top of a river valley that has mega tons of gravel/limestone and sand.Wondering if the limestone/gravel and sand can de-juice a storm or maybe it's a government thing, we live close to a major base in the boondocks.

Anyway, my county has seen it share of tornado's what is interesting many take similar paths every time, right up the river valley or along state roads and highways.

Strange...

Interesting way to look at it... maybe the prayers of the people who are sick of repairing storm damage are being answered. Also, geographically with the huge swoop of Lake Michigan, the polar vortex can change so much at any given moment.
